" ARTIFICIAL STONE.

SPECIFICATION forming part of Letters Patent No. 312,356, dated February 1'], 1885.

Application filed January 12, 1885. (No specimens.)

To all whom it may concern:

Be it known that I, JOHN D. KING, a citizen of the United States, residing at Fairbury, in the county of Jefferson and State of Ne- 5 braska, have invented certain new and useful Improvements in Artificial Stone; and I do hereby declare that the following is a full, clear, and exact description of the same.

My composition consists of the following in- 10 gredients, viz: sand, cement, water, soluble glass, borax, saltpeter, dried alum, and salt, which are to be used and combined in the manner and in the proportions hereinafter specified.

In preparing this composition, I take four parts of clean sand and add thereto one (1) 4 part of cement, ebest English Portland K. B. S. him preferred.) After the sand and cement have been completely mixed I dampen 2o them with asolution composed of the following ingredients, which are first thoroughly mingled'by agitation, viz: pure water twelve gallons; solubleglass fourpoun s; orax one pound; sa tpe er, one, and one-half pound; zs driedalum onealfpopnd. The mortar thus formed is then molded into any desired shape, or isspreadto any required thickness. About six (6) hours after the mortar has been taken from the molds or spread I saturate it thor- 3o oughly with a brine composed of common salt and water in the proportion o a out three A mm-m s litg uswsww (3) pounds of salt to twelve (12) gallons of water.

0 not restrict myself to the precise'proportions of the articles composing said composition, as they may be slightly varied, if necessary. The mortar should be rendered con1-. pactwhenbeingfinallyshaped. ThisIaccomplish when placing it into molds by gently ramming or forcing it into them, and when spreadingitbypressingit firmly. Thestonethusproduced can be molded into any desired or required useful or ornamental design or shape, and also can be safely and conveniently used in any capacity in which natural stone or brick are employed.

Having thus fully described my invention, what I claim, and desire to secure by Letters 1; Patent of the United States, is- 1 The herein-described composition of matter 50 to be used in the manufacture of artificial stone, consisting of sand, cement,water, soluble glass, bp ax, saltpeterfdfiedalum, and salt, in the proportions specified? In testimony that I claim the above. I have hereunto subscribed my name in the presence? of two witnesses.
